Why choose SL925 LED linear lighting?

Outstanding energy efficiency

The SL925 LED linear lighting demonstrates excellent energy efficiency, with a power factor (PF) of ≥0.9. It also delivers high luminous efficacy, reaching up to 100Lm/W. Compared to traditional lighting types such as fluorescent lamps and CFLs, it significantly reduces energy consumption and electricity costs. The energy efficiency advantage of LED linear fixtures makes it the preferred choice for sustainable lighting solutions.

Long lifespan

The SL925, featuring LED chips, boasts an ultra-long lifespan. Based on tests conducted by kosoom engineers, the SL925 typically has a lifespan of up to 50,000 hours. This greatly reduces the frequency of maintenance and replacement for LED linear fixtures, resulting in lower repair costs and inconvenience.

Environmentally friendly

The SL925 is environmentally friendly. Neither the chips inside the fixtures nor the various accessories, including the housing, contain harmful substances such as mercury. Even after reaching the end of its lifespan, the SL925 is highly suitable for recycling and does not have a negative impact on the environment.

SL925 LED linear lighting applications

Office spaces

The SL925 LED linear lighting fixtures are commonly used in office environments, such as open-plan offices and individual offices in office buildings. They are also suitable for conference rooms. In these office spaces, they are typically used for task lighting on desks. The fixtures are suspended above the desks, and the beam angle can be selected based on the installation height, providing various options to suit your lighting needs, installation height, and desk size.

Commercial spaces

The SL925 is also suitable for other commercial spaces, such as management offices in commercial areas and offices for property personnel. It can fulfill various requirements for color rendering index. If you have a personal independent studio and require a high color rendering index, the SL925 is the ideal choice. We offer customization with a CRI ≥ 95.

For supermarket or retail checkout areas, the SL925 is an excellent choice. These areas require high-quality and bright lighting to ensure smooth checkout operations. The high color rendering index also enhances the final confirmation and display of products, enhancing the shopping experience for customers.

SL925 LED linear lighting installation

Tools you will need

Pencil or chalk, measuring tape, electric drill, screwdriver, electrical tester.

Installation steps

Step 1: All active power sources should be turned off before starting the installation. Use an electrical tester to ensure there is no live power on the circuit. If the indicator light on the electrical tester does not turn on, it means the power has been safely disconnected.

Step 2: Refer to the fixture design drawings to determine the installation location of the SL925 LED linear lighting. Mark the positions on the ceiling where the installation brackets need to be drilled using a pencil. Then, drill holes at the marked positions and secure the installation brackets to the ceiling. Note that some specific installations may require additional hooks to complement the ceiling brackets, which we do not provide, but you can easily purchase them at any DIY store.

Step 3: Use steel wire or suspension rods to fix the SL925 LED linear lighting to the ceiling brackets and adjust the fixtures to the desired height. You can adjust them based on the instructions provided in the lighting design drawings and ensure the stability of their installation.

Step 4: Retrieve the reserved power wires and use an electrical tester to confirm that the power is disconnected. Then, turn off the power again. Use wire connectors to connect the wires of the LED linear lighting to the reserved power wires. Connect the grounding wire of the fixture to the grounding wire inside the ceiling.

Repeat this step for all remaining embedded LED linear lighting fixtures.
